The feet of the gecko cling to virtually any surface. This scanning electron microscope image shows one of the branching hairs, or setae, on the sole of a gecko's foot. These hairs nestle into nanoscale niches on the contact surface....

The gecko's amazing ability to cling to vertical or inverted surfaces is due to the interaction between nanoscale structures on its feet and tiny crevices on the wall or ceiling. The soles of gecko feet are made up of overlapping...
